1. 1. Numerical modelling of the rock fracture process under mechanical loading

   Författare :Hongyuan Liu; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

   Sammanfattning : The fracture of rock has been the subject of the extensive research in the mechanical fragmentation. With the rapid development of computing power, interactive computer graphics and topological data structure, numerical tool has become a good tool to gain some insights into the problem of rock fracture.

3. 2. Numerical modelling of the rock fragmentation process by mechanical tools

   Författare :Hongyuan Liu; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

   Sammanfattning : The rock fragmentation process by mechanical tools is investigated using numerical method. The rock and tool interaction code (R-T2D) is first developed on the basis of the rock failure process analysis (RFPA) model and the finite element analysis (FEA) method. LÄS MER
